To prevent the looseness of a tray and to reduce the number of part items of a device so as to simplify assembling work and to reduce cost by integrally forming a protruding part at a tray, and making the protruding part come in sliding contact with a support face of a container holder while coming in pressure contact with it by elasticity.

A container holder 7 is pulled out of a case 2 when in use, and a tray 14 has a container holding part 15 for supporting the bottom part of a drink container 13 when the drink container 13 is inserted in a container holding hole 12 of the pulled-out container holder 7. Each protruding part 21 is protrusively provided at the free end part of a cantilever type tongue piece 22 formed integrally with each arm 16 of the tray 14, and the tongue piece 22 is elastically deformable bending in a C-direction with the base end part as a fixed end. When the container holder 7 is pulled out or pushed in, moderate sliding resistance caused by pressure contact between the protruding part 21 and a support plate 11 is imparted to the tray 14, so that looseness is not generated even if the vibration of an automobile is transmitted, and cost can be reduced.
